Definitions

  • the present invention relates to a cartridge with ceramics discs for use in mixing cocks,faucets and the like, comprising a sealing element of the anti-hammering type.
  • ceramics cartridges and discs for use in mixing cocks and the like conventionally comprise gaskets arranged at the outer face of the fixed ceramics disc,which gaskets seal the cold water and warm water inlet ducts.
  • the aim of the present invention is to solve the above mentioned problems,by providing a cartridge with an anti-hammering sealing element which provides a proper sealing without causing the gasket to be displaced from its seat.
  • a main object of the present invention is to provide a ceramic disc cartridge for cocks and the like which is very silent and reliable in operation.
  • Another object of the present invention is to provide such a sealing element which is so designed as to greatly reduce the pressing force between the ceramics discs of the cartridge,so as to correspondingly reduce the operating effort to be applied to the cock operating lever.
  • a ceramics discs cartridge for mixing cocks and the like, which has been generally indicated at the reference number 1,comprises a box-like body 2, which is closed at the top thereof by a closing cap 3,operating as a holding and articulation element for the operating lever driving the cartridge.
  • a fixed ceramics disc 5 Inside the cartridge there is arranged a fixed ceramics disc 5,which is provided with ports 6 and 7 for the inlet of hot water and cold water,as well as an outlet port 8 coupled to the delivery cock.
  • a movable ceramics disc 10 Slidably with respect to the fixed ceramics disc 5 there is provided a movable ceramics disc 10, provided with an operating or driving opening or port 11 which,in a known manner,can be translated and rotated so as to engage,either partially or fully, the ports 6 and 7 and to adjust,accordingly,the delivery and mixing of water.
  • the movable ceramics disc is held by a driving body 20,which comprises silencing fins,indicated at 21,which can be two,three or four and which, in addition to engaging with the port or opening 11, also operate to convey and separate the fluid threads, thereby providing a noisless operation for the cock.
  • a driving body 20 which comprises silencing fins,indicated at 21,which can be two,three or four and which, in addition to engaging with the port or opening 11, also operate to convey and separate the fluid threads, thereby providing a noisless operation for the cock.
  • the provision of the silencing fins 21 generates a sectorial division of the water flow, thereby preventing localized turbulences susceptible to generate noise.
  • An important aspect of the present invention is that at the hot water and cold water inlet ports 6 and 7 there is provided a sealing element preventing the gasket,as a water hammering occurs,from threading between the bottom of the body of the cartridge 2 and the fixed ceramics disc.
  • a protecting tubular portion 30,of a comparatively rigid material which is housed within the ports 6 and 7 and which,in turn,houses a gasket 31 in its inside,said gasket being made of a rubber having a comparatively small stiffness,preferably a Shore hardness of 40-50.
  • annular ribs,indicated at 35 are provided on the inner surfaces of said gaskets, which ribs allow to further increase the sealing in addition to assuring a proper location of the gasket,even in a water hammering condition.
  • the used materials though the best results have been obtained by using the above mentioned materials,as well as the contingent shape and size,can be any according to requirements.
